A method for assigning swappable battery packs to electric aircraft includes receiving, at a computing system, status information for a plurality of battery packs located at at least one battery swapping location, wherein the status information comprises states of charge and states of health for the plurality of battery packs; determining, by the computing system, energy requirements for a plurality of electric aircraft based at least in part on flight plans for the plurality of electric aircraft; determining, by the computing system, assignments of at least a portion of the plurality of battery packs to the plurality of electric aircraft based at least in part on the states of charge and states of health of the plurality of battery packs and the energy requirements for the plurality of aircraft; and swapping at least one battery pack into at least one aircraft based on the determined assignments.

Methods and systems are provided for adjusting regenerative braking in response to normal loads applied to each of a vehicle's wheels coupled to an electric machine. In one example, a regenerative braking torque for a wheel may be adjusted in response to a normal load that is applied to the wheel as wheel load changes during vehicle braking.

The present invention relates to the fields of mechanical and electronic engineering, focusing on energy efficiency on freight transport systems. More specifically, the invention applies to Long Combination Vehicles (LCV), in which the semi-trailer is provided with an auxiliary traction system, such as electric traction with regenerative braking, for example. The invention provides means for controlling the actuation of the auxiliary traction, which provides safe use and enhances economic and environmental savings in freight transport. In one embodiment, the invention provides a system for managing the auxiliary traction on a road implement that provides improved, safer drivability of the set.

An apparatus includes a photodetector and a memristor coupled to the photodetector. The photodetector is configured to receive and convert optical signals to electrical signals to program the memristor to an on or off state. The apparatus further includes a ring resonator coupled to the memristor and configured to modulate light based on the on or off state of the memristor.

A control system for a tiltable vehicle may include a motor controller configured to respond to backward or reverse operation of the vehicle by hindering a responsiveness of the control system (e.g., proportionally) and/or eventually disengaging a drive motor of the vehicle. Accordingly, a user may intuitively and safely dismount the vehicle by selectively commanding reverse operation. In some examples, the backward direction may be user-defined.

The control device includes a vehicle required braking force acquisition unit that acquires a vehicle required braking force that is a required value of the braking force applied to the vehicle, and a roll control unit that controls the rolling motion of the vehicle by adjusting a distribution ratio of the braking force with respect to a target wheel including at least one of a rear wheel on an inside during turning and a front wheel on an outside during turning of the vehicle when the braking force is applied to the vehicle according to the vehicle required braking force under a situation where the vehicle is turning.

In a drone system in which a drone and a movable body operate in coordination with each other, the drone performing a predetermined operation in an agricultural field, the movable body being capable of moving with the drone aboard and allowing the drone to make a takeoff and a landing, the plan determining section determines a flight plan for the drone and a movement plan for the movable body in accordance with the flight plan, and the instructing section instructs the drone to execute an operation in accordance with the flight plan and instructs the movable body to move or to be on standby in accordance with the movement plan.

A vehicle controller for avoiding a collision of a vehicle and a method thereof are provided. The vehicle controller includes a drive motor that supplies electric power for a behavior of a vehicle, sensors that obtain information outside the vehicle and information inside the vehicle, and a controller that estimates, when detecting evasive steering of a driver in a collision situation based on the information outside the vehicle and the information inside the vehicle, a front wheel slip angle and a rear wheel slip angle, and controls the drive motor based on the front wheel slip angle and the rear wheel slip angle.
